Abstract β-Elimination of acetic acid was elaborated in our synthetic method of a tricyclo[4.1.0.02,7]hept-4-en-3-one (tropovalene) skeleton. Presented was a new synthetic method of this skeleton, which consists of a reaction sequence of 1,4-addition of propanethiol to bicyclo[3.2.0]hepta-3,6-dien-2-one, photochemical construction of bicyclobutane skeleton, oxidation, and thermal elimination of sulfenic acid.

三环[4.1.0.02,7]Hept-4-En-3-One骨架的一些制备方法

摘要 在我们的三环[4.1.0.02,7]hept-4-en-3-one（原戊烯）骨架的合成方法中详细阐述了乙酸的β-消除。提出了该骨架的新合成方法，包括丙硫醇的1,4-加成到双环[3.2.0]hepta-3,6-dien-2-one的反应顺序，双环丁烷骨架的光化学构建，氧化，和次磺酸的热消除。
